I saw now (that I started to think about possible problems that can
arise) that my function Goto_Node_Id can fail if a wrong Id is given. I
guess it is better to turn it into a function and return false if the
Node_id cannot be found.

I have noticed that some libraries only raises a lot of exceptions and
leave it at that. That was the reason for my questions. As I also read
that exceptions can be a monstrosity if over used.
